Remove a control

You don't have to do that. Simply make your control to fail at creation time after the evaluation period. Don't make the host app crash, just make sure your control does nothing. You can print some text instead: "Evaluation period finished. Show me the money." or something. :D

If you're using Visual Studio 6.0, the information for the control is embedded in the .dsw file. You should notice the guid for the control. If you remove it (carefully), it should remove it from the project. NOTE: Since this needs to be done manually, it is recommended that you make a back up copy of the .dsw file.

No problem PadexArt,you all are helping me so much,and i really appreciate!

Mike's right, you need to manually change your dsp and probabbly the resource file as well.
What have i got to edit?the dsp or the dsw?or both?

The .dsw contains the control reference. You'll also need to remove the control from any dialog resource, and, delete any wrapper class(es) that provide access to the control.

No, the DSW file does not contain refferences to the controls used in a project.

The DSP file contains refferences to the implementation files of the wrapper classes generated for the controls if any.

The resource file(s) are the problem here as they are the ones containing the refferences for the controls.

Indeed. :blush: I seldom use controls this way (Insert in project) so none of my DSW's contained such refferences.

Follow the steps in the article. Or, alternatively, you can just delete the lines that contain the guids for the controls from the .dsw file.
